The actuation point determines when a press becomes a click.
Press a mouse button, and the click does not need to reach the bottom of its travel before the mouse registers it. The actuation point is the depth at which that press counts.
A conventional microswitch sets that depth in hardware. On a mouse with adjustable actuation, you can move the point within the range provided by the current Launcher and product configuration.
In short
Actuation point: The depth at which a button press registers.
Adjustable actuation: A setting that changes where a press registers within a configured range.
Shallow setting: Smaller movements can register sooner, leaving less margin for an unintended click.
Deep setting: More movement is needed before a press registers, adding a little margin against accidental clicks.
Total click travel: The full distance the button can move from rest to bottom-out. It is a separate measurement.
What is a mouse actuation point?
The actuation point is the depth at which a press registers. Until the button reaches that depth, the mouse does not treat the movement as a click. This depth controls when the click registers, but it does not by itself set the sound, weight or tactile feedback you feel.
A traditional mechanical microswitch generates its signal at a depth determined by its structure, so that depth is fixed in hardware. A mouse that tracks button position continuously can alternate between configured depths. This is what makes adjustable actuation possible.

Actuation point vs total click travel
Total click travel is the full distance a mouse button can move, from rest to bottom-out. The button can keep moving after a click registers, so an adjustable point and a set total travel can coexist on the same mouse. One parameter does not replace the other.
Actuation point and total click travel are measured from the same rest position. The labels show which distance each parameter measures.
A product example: the G6 HE
The Keychron G6 HE offers 12 adjustable actuation steps. Its product page also lists 0.65 mm ± 0.07 mm of total click travel. That figure describes the button's full movement, with a manufacturing tolerance, and is not a trigger point.
Changing the actuation point does not change that overall travel; it changes where a press registers along the way. Use the current Launcher and product page for the values available in your configuration.
How to compare actuation points between mice
Match the labels before comparing the numbers. Compare an actuation point with another mouse's actuation point, and total click travel with total click travel.
Read each point within its own adjustment range. On one mouse, the same depth may sit near the shallow end; on another, it may be near the middle. Also check where the tactile feedback occurs and how much travel remains after the press registers. These details affect how a full press feels.
Step counts, ranges and travel figures can differ between product pages, reviews and older guides. For a specific model, use its current product page as the reference.
How actuation depth affects click response
A shallower setting can let a small movement register sooner, leaving less room for an unintended click. A deeper setting requires more travel before the press registers, adding margin, but light or hesitant presses may not count. The right choice depends on how you use the mouse and how your hand rests on it.
The timing difference between two settings can be estimated from the distance between them and your finger speed:
extra distance = deeper setting - shallower setting (mm)illustrative time difference = extra distance (mm) / finger speed (mm/s)
If the settings are 0.1 mm apart and your finger moves at 50 mm/s, the result is 0.002 s, or 2 ms. This is a rough calculation, not a measured latency gain. The actual difference depends on the specific settings and your own motion.
Click feedback and click detection can come from different parts of the switch, so the on-screen result may arrive slightly before or after the snap you feel. After changing the setting, check whether the click still feels predictable in normal use. Change one thing at a time before assuming that the actuation depth alone explains any difference.
How a setting feels depends on your grip, hand position and clicking style.
Does a shallower actuation point make the mouse faster?
A shallower point can make the same press register earlier in the button's travel. That is only one part of the path from your finger to the game. The mouse still has to sense, process and report the input, and polling rate, firmware, the connection and the rest of the system all affect timing.
Mechanical and magnetic switches also detect a press in different ways. Magnetic sensing does not rely on contacting metal parts, so it avoids the contact-bounce filtering used by mechanical microswitches. That does not make total latency zero, and the durability of the whole mouse still depends on its overall design.
How it differs from Rapid Trigger
The actuation point determines when a press counts on the way down. Rapid Trigger determines how soon the button can accept another press after it starts to return.
Actuation registers the press. Reset determines when another press can register.
Should you adjust it?
If the button occasionally registers before you are ready, try one step deeper. If short, intentional presses often fail to register, try one step shallower. Start near the middle of the range, move one step at a time, and test each change during normal use.
On the G6 HE, you can adjust actuation in Keychron Launcher. The G6 HE guide to Keychron Launcher shows where to find the controls. To check the model's advertised configuration, see the G6 HE product page.
FAQ
Is total click travel the same as the actuation point?
No. The actuation point is the depth at which a press registers. Total click travel is the full movement from rest to bottom-out.
Is the G6 HE's 0.65 mm the actuation point?
No. The product page lists 0.65 mm ± 0.07 mm as total click travel. The G6 HE also offers 12 adjustable actuation steps in Launcher.
Is a lower actuation point always faster in play?
It can make the same press register sooner, but it does not guarantee lower sensor, connection or system latency. Other parts of the input path still affect timing.
Does adjustable actuation replace the tactile click?
That depends on the switch design. Adjustable actuation changes when the press is detected. It does not determine what tactile feedback the button provides.
Is the actuation point the same as Rapid Trigger?
No. The actuation point affects when a press registers. Rapid Trigger affects when the button can accept another press after it begins to return.
